Data Sheets

Q. Please could you tell me how long it takes to charge up the battery on the Kidde radio interlinked bases?

A. Hello, it takes 24 hours to fully charge the back up battery on the Kidde radio interlinked bases.

Q. Are the KE1SFWRF, KE2SFWRF and KE3SFWRF units 'stand-alone' or do they require an additional base unit?

A. Safelincs supplies RF bases with these products which enables radio interlinking between units, so they do not require any additional components.

Q. How can we test the alarm to make sure it is working?

A. The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.
